Abstract
The invention relates to a method for functionally testing a filling level sensor which measures the filling level of a liquid in a tank, in which method a change in filling level that is measured by the filling level sensor is compared with a calculated change in filling level. According to the invention, the calculated change in filling level is determined from a measured change in temperature of the liquid.
